w'meo SPEGIFICATION :t'orming part Of Letters Patent ING. 702,754, dated June 17, 1902.

Application filed October 4', 1901 Serial No. 7 7,575-' (No model.)

nois, have invented certain new and useful Improvements in'Windows, of which the .fol-

lowing is a specification.

This invention relates to improvements in windows, and more particularly to fireproof-,- windows of that class which have their frames and casings made of sheet metal.

The object of theinventionisto-provide an improved construction for securing the glass in place in the windows of this character; and to this end it consists in the matters herein set forth, and particularly pointed out in the appended claims.

In the drawings, Figure 1 is a frontelevation of a metal window constructed in accord-' ance with my invention and comprising a lower stationary and an upper pivoted or swinging sash, to both of which my improvements are applied. Fig. 2 is a sectional side elevation thereof. Fig. 3 is a top-plan sec tion taken through the stationarysash on-line 3 3 of Fig. 1. Fig. 4 is a top plan section taken through the swinging sash on line 4 4 of Fig. 1. Fig. 5 is a fragmentary perspective view indicating the manner of inserting the glass in the sash. Figs. 6, 7, 8, and 9 are top plan sections further showing the manner of inserting the glass in the. sash. Figs. 9 and 10 are reverse perspective details better showing the construction at the base of the middle bar of the sash. Fig. llis a detail in sectional elevationshowing the manner in which the middle barand clamping-bar are connected to the casing at their upper ends.

Fig. 12 is a top plan detail thereof, taken on line 12 12 of Fig. 11,- Fig. 13 is a perspective detail showingithe formation of thewin-' (low-casing at its point of juncture with the middle clamping-bars. Fig. 14. is-.a perspec hive detail of the upperend of the clamping ar. ing-bar as a whole. Fig. 16 is a perspective detail showing the location of the screw-plates in the middle bars: Fig. 17 is a similar View showing the relative positions of the middle and clamping ,bars when placed in position. with theglass between'th'em. Fig 18 is a similar view showing the manner of securing the clamping-bar in place by clamping-screws engaging the screw-plates in the middle bar.

Fig. 15 is a side elevation of the clampupper section 'is .in this instance provided with a swingingsash C, while the sash D of the lower sectionis made fixed or stationary. -It will, however, be'understood that in so far as the present invention is concerned it is immaterial whether the window casing comprises one or more sections or whether the sash of any section is fixed or is arranged to slide or swing, my improvements being equally applicable in either case.

Extending around the inner margin of each sash is a'grooveL'made of suitablewidth to receive the edges of the panes of glass G and of a depth desirably about equal to its width, except along the upper edge of the s'ash,where the groove takesthe form of an open slot 2, into which the 'glass'maybe thrust consider ablyfarther 'thanlthe" distance which it normally occupies when in place, Figs. 2 and 5.

The glass G for each sash is provided in a plurality of panes-in this instance two -the aggregate width of which is made somewhat less than the extreme inner width of the sash from the bott'omof the groove 1 on one side to the bottom of. the same groove on the other. This permits the glass to be inserted by proceeding in the manner indicated in'Figs. 5 to 9, inclusive. Theupper edge of the first pane is slipped angtilarly up through the slot 2, as shown in Fig. 5', 'and'the whole pane is side of the sash, as-shown in Fig. 7. r'This leaves a space between its other lateraledge and the other side of the sash wideenough jto receive the second pane, which is then inserted in the same manner 'as' 'the'first pane until it'occupies the position shown'in"Fig.-'8,

'whereupon'it is moved sidewise' away "from the first pane until its lateral edge'enters the groove 1 on the other side of, the 'sash','-as shown in Fig. 9. The glass is then secured in thisposition, as follows: Midway between its sides the sash is provided with a vertical bar 3, located in front of the groove 1, with its rear face in the same plane as the front edge of said groove or in line with the front surface of the inserted glass. This bar covers the adjacent edges of the two panes of glass on their front sides and affords a ledge against which these inner edges of the glass rest. Operating in conjunction with this middle sash-bar 3 is a clamping-bar 4, having forwardly-projecting flanges 5, which enter between the panes, so as to prevent their lateral movement, andlateral flanges 6, which project back to the glass and hold it firmly against the front bar 3. This clamping-bar is herein shown as secured in place by screws 7, which extend through the bar into screwplates 8 in the front bar 3 and by turning up which the glass may be held between the clamping-bar and front plate as tightly as desired. This clamping-bar is putin place after the panes have been inserted and moved laterally into their final positions, as shown in Fig. 9, and the tightening of its screws 7 completes the glazing operation.

In the ease of the lower or stationary sash the manner of applying the clamping-bar is somewhat similar to the first operation of inserting the glass-that is to say, its upper end 9, which is extended above its flanges 5 and 6, is thrust angularlyup through an aperture 10 in the top of the sash, after which the bar is swung forward into vertical position against the glass and then slipped down until its lower end 11, which is extended below its flanges 5, enters a groove 12, formed parallel and adjacent to the groove 1 in the bottom of the sash. This brings the screw-holes in the bar4: into register with the threaded holes in the plates 8 of the bar 3 and enables the screws 7 to be inserted and turned up to clamp the glass in position, as above described. The bar 3 of the lower sash is herein shown as cut out at 13 to fit over the outer angle of the sill or bottom of the sash and as secured thereto by a rivet 5 or the like, while at its upper end it is permanently locked within the top of the sash by extending up through an opening 14: thereof. In case of the upper or swinging sash this bar is shown as simply riveted to the top and bottom of the sash,while its clamping-bar is secured in place only by the screws 7. In either case, however, the bar 3 will ordinarily be a permanent part of the sash.

One great advantage of the construction described is that it enables the window to be glazed from the inside of the building and does not'require any attention or manipulation from without, as is commonly necessary in fireproof windows of this character. Windows so constructed may, furthermore, be made of any desired width and arranged to contain as many panes of glass as may be necessary to glaze the desired width of the sash without regard to the width of the panes, since it is only necessary to provide as many additional bars 3 and 4: as are needed in clamping the adjacent edges of each pair of panes. Obviously many changes may be made in the details of the construction shown without de parture from the broad spirit of the invention claimed.

I claim as my invention 1. In a window, the combination with a plurality of panes of glass, of a sash grooved to inclose said panes of glass, a bar fixed to and extending across the sash in front of the plane of the groove and past which the panes may he slid laterally to introduce them to and withdraw them from the lateral portions of the groove, a clamping-bar interposed be tween the panes when slid into the side grooves and bearing against their adjacent edges opposite to the fixed bar, and means for detachably securing the clamping-bar in place, substantially as described.

2. In a Window, the combination with a plurality of panes of glass, of a sash grooved. to inclose said panes of glass, a bar fixed to and extending across the sash in front of the plane of the groove and past which the panes may he slid laterally to introduce them to and withdraw them from the lateral portions of the groove, a clamping-bar interposed between the panes when slid into the side grooves and bearing against their adjacent edges opposite to the fixed bar, and clamping-screws detachably securing the clampingbar to the fixed bar, substantially as described.

3. In a window, the combination with a plurality of panes of glass,of ametal sash grooved to receive said glass, the upper portion of said groove being an open slot through which the glass may be abnormally projected, a bar extending across the sash in front of the groove and against which the adjacent edges of the panes bear on their front sides, a clampin g-bar interposed between the panes and bearing against their adjacent edges on their rear side, and means for detachably securing the clamping-bar in place, substantially as described.

4. In awindow, the combination with a plurality of panes of glass, of a metal sash grooved to receive said glass, a bar extending across the sash in front of the groove and against which the adjacent edges of the panes bear on their front sides, a clamping-bar interposed between the panes and bearing against their adjacent edges on their rear sides, screwplates secured in the cross-bar, and screws passing into the screw-plates tosecure the clamping-bar detachably in place, substantially as described.

In testimony that I claim the foregoing as my invention I afiix my signature, in presence of two subscribing witnesses, this 1st day of October, A. D. 1901.
